Replace Starter (Again)

There were some strange noises coming from the starter one morning, so I took it straight to the shop that fixed it the first time. They said:

“Visually through the inspection plate we could not see any problems with the ringgear. We removed the starter motor we had installed in October. We bench tested this motor and it worked okay on the bench. We checked with our vendor and they had a replacement in stock. We then double checked with a different vender (sic) and found that they were showing a different part number. We hae (sic) installed this other part number and it is starting fine at this time.”
